What is weathering?
Weathering is the breaking down of earth materials by wind, water, and ice.
What is a nonrenewable resource?
Nonrenewable resources are resources that can’t be renewed in our lifetime. They are resources that cannot be replaced as fast as they are used up. Nonrenewable resources take millions of years to form like coal, oil, and natural gas.
What is conservation?
Conservation is an effort to preserve and protect of something.
What are the 3 parts of the water cycle?
Evaporation, condensation, and precipitation
True or False - the appearance of the Moon changes over time in a predictable pattern?
True - as the moon orbits the Earth, we see the light from the sun reflected off its surface.
Name 4 types of precipitation.
Rain, sleet, snow, and hail
What is erosion?
Erosion is the movement of broken down earth materials by wind, water, and ice.
What is a renewable resource?
A resource that is used repeatedly and replaced naturally. Water, air, plants, animals, and soil are some examples.
Why should we conserve nonrenewable resources?
We will run out of these resources to use.
What provides the energy that powers the water cycle?
The sun provides the heat energy that powers the water cycle.
The Sun rises in the east causing shadows in the morning to fall in which direction?
West
Scientist collect temperature in degrees Celsius. What is a warm temperature in Celsius?
Between 20 and 36 degrees Celsius.
What is deposition?
Deposition is the build-up of earth material in another location.
Which TWO of the following is NOT a nonrenewable resource and why?
trees, water, sun, horses, gasoline, cotton, lettuce, pigs, coal
Gasoline and coal are both nonrenewable resources. They are nonrenewable because they are fossil fuels that would take millions of years to be replenished.
What is one pro and one con of fossil fuels?
Answers will vary
Pros: inexpensive, many fossil fuels available
Cons: nonrenewable, cause pollution
Where does evaporation take place?
Water is evaporated from both land and water.
The Sun sets in the west causing shadows in the afternoon to fall in which direction?
East
Scientist collect temperature in degrees Celsius. What is a cool temperature in Celsius?
Between 9 and 18 degrees Celsius.
How can the surface of a mountain be changed by weathering, erosion and deposition?
The rock of the mountain could breakdown from weathering. The weathered material could erode and be deposited at the bottom of the mountain.
Which TWO of the following are both renewable resources and why?
rocks, oil, cattle, coal, minerals, plastic, grass, natural gas.
Cattle and grass are both renewable resources. Cattle and grass can both be replenished.
Why do we need to conserve water?
Water needs to be conserved so we have enough to drink, cook with, clean with and have enough for plants and animals too!
Is water a renewable or nonrenewable resource?

Where does the energy for shadows outside come from?
The Sun
What causes the different seasons on Earth?
The tilt of the Earth’s axis as it orbits the Sun.
What steps would you take to design an investigation on weathering?
Answers will vary.
Do you think soil is renewable or nonrenewable?Explain why.
Answers vary
Scientists and citizens in an area are concerned about soil conservation. What are some steps they can take to reduce the impact of erosion and deposition on the local soil?
Answers will vary
What percentage of Earth's water is fresh water?
3%
About how many days does it take for the Moon to go through a complete cycle of all its phases?
The Moon goes through a complete cycle of all phases in about 29 days
How could you design an investigation to explore how and when snow forms?
Observe and record what weather is like on days where snow forms.
